What is the golden flower of black tea
|
The so-called golden flower of black tea is actually a yellow granular fungus. Its scientific name is Eurotium cristatum. It mainly exists in the Fubrick tea of black tea. An important process of Fubrick tea is the flower, which is a fermentation process. It has a very good health care effect on the human body, can improve the quality of tea, has a good antioxidant effect, and has a very good health-preserving effect on the body. What is the golden flower of black tea? "Golden Flower" is actually a kind of probiotic with multiple health functions that grows through a specific process under specific temperature and humidity conditions during the processing of Anhua black tea and Fu brick tea. The yellow cleistothecia resemble tiny spots that are evenly attached to the Fu brick tea, commonly known as "Golden Flower". What changes does “flowering” bring to the quality of Fuzhuan tea? Studies have shown that after the Fu brick tea has been "bloomed", its amino acids, tea polyphenols, flavonoids, caffeine, soluble sugars and water extracts have decreased to varying degrees. Caffeine decreased by 10.85%, which helped reduce the bitterness of Fuzhuan tea. Flavonoids in tea polyphenols decreased by 51.52%. Amino acids decreased by 36.84%. The decrease in amino acids and their reaction and transformation with sugars are important reasons for the varied aroma of Fuzhuan tea. The content of soluble sugar and water extract changed the least, only 5.9% and 2.34% respectively. What’s so special about the golden flowers in black tea? The formation of "golden flowers" is a process of production, reproduction, oxidation and polymerization of a large number of microorganisms. The secretions produced during the reproduction and oxidation of microorganisms effectively reduce the rough taste of Fu brick tea, increase the mellow taste, and play a positive role in improving the taste quality of Fu tea. "Golden Flower" has special health-care effects. Due to the presence of "golden flowers" or Eurotium cristoides, Fuzhuan tea has a color, aroma and taste different from other teas, and its health benefits such as promoting digestion, lowering blood lipids and weight loss, and treating cardiovascular diseases are more prominent. Five special features of "Golden Flower" 1. Improve the quality of tea. The Aspergillus cristobalis uses the nutrients obtained from tea leaves to carry out its own metabolic transformation to meet its own nutritional needs. At the same time, it produces extracellular enzymes such as polyphenol oxidase, pectinase, cellulase, protease, etc., which catalyze the oxidation, polymerization, degradation, and transformation of substances in tea leaves, achieving the unique color, aroma and taste of Fuzhuan tea. 2. It has antioxidant effect. After absorbing the tea polyphenols in Fuzhuan tea, Eurotium cristatum secretes and produces a variety of biologically active ingredients with the ability to eliminate free radicals. What’s so special about the golden flowers in black tea? 3. Resist harmful bacteria. During its growth process, Eurotium cristatum produces metabolites that are unfavorable to the existence of other microorganisms, thus resisting the growth of harmful bacteria. 4. Increase the activity of enzymes. Eurotium cristobalium can increase the activity of amylase and protease, and at the same time resist the activity of lipase. 5. Regulate and maintain the balance of intestinal microbial flora. Although the composition of E. coronaria has not yet been determined, the chitin and chitosan contained in the fungal wall are a special type of dietary fiber that can promote the formation of Clostridium XIVa clusters in the intestines and reduce high-fat obesity. |
